I'm debating running the same size tires all around so I can rotate them. I'm running stock 19s who all does it? I'd like to go as wide as I can. 15k miles after my eibachs and alignment and the insides of my front tires are destroyed. I know I need q camber arm upgrade to solve that problem and that's coming but I still like the idea of rotating my tires. My car isn't tracked or raced. Just a commuter. Thanks.

 

im running same size for winter on my 19" 245 all round seem ok

 

Technically speaking, when you have a car balanced the way it is stock, and then go to your proposed setup:
You are decreasing the rear contact patch. You are therefore reducing the rear grip. You are therefore increasing the amount of hypothetical oversteer in any given cornering situation, or "stress" situation. The result is a higher percentage chance of the rear end of your car coming around.
That said, I personally prefer oversteer that I can control, and really, really like squared setups like 245 all around like you suggest.
Cheers,

 

I noticed you added performance MODs, why downgrade your tire contact?

 

I recently went to a squared setup with 245's. My question is can the tires be rotated since the wheels have a width and offset difference between the front and back?

 

Will be fine running all same around. Common winter option.

 

Stockers? Yeah no worries

 

Downgrade? My rear tires were 245's stock so how would I be downgrading going to 245's all the way around vs. just having 245's in the back?

And fwiw, I said screw it and went with 245/40/19 in the front and 275/35/19 in the rear. Hankook ventus v12. Loving them so far.

 

Yep, stock wheels.... thanks for the info!

 

Even if you went with 245 all around you couldn't rotate them. The TPMS sensor light would turn on and the tire widths are different in the front then in the rear.

 

How could tire widths be different if they were all 245/45/19? Or are you talking wheel width? And how does the tpms know which part of the car it's on?

 

You could rotate them it would just require a tire dismount. Anf fyi our tpms is not wheel specific like earlier years that reported psi. I swapped wheels from side to side on my 09 370z and tpms never tripped.
